摘要： A cutting tool (10; 30; 50) is provided which comprises a curved cutting edge (13; 33; 53) at a nose (12; 32; 52), a pair of straight cutting edges (14, 14: 34, 34; 54, 54) between which the nose is located, and a chamfer (15; 35; 55) extending along the cuzved cutting edge and the straight cutting edges. A portion of the chamfer extending along the curved cutting edge forms a curved ridge (15a; 35a; 55a) at the junction with a tool face (17; 37; 57) and increases in width from a junction (P1) of the curved cutting edge and each of the straight cutting edges to a midpoint (Q) of the curved cutting edge when observed in plan.

摘要： The invention relates to an indexable cutting insert for face milling of engine blocks of cast iron. The insert (10) has a free surface (16) and a clearance surface (13A) and a cutting edge extending peripherally about the insert. The corners of the insert have a relatively large radius and therefore the setting angle gets close to zero degrees during machining of the engine block when the insert gets close to the border line of the work piece. The free surface (16) and the clearance surface (13A) enclose an acute angle and therefore the insert has a positive cutting geometry. A land (18) is provided between the the free surface (16) and the cutting edge (19). The land (18) has a width increasing towards each insert corner.
摘要翻译：本发明涉及一种可转位的切削刀片，用于铸铁发动机缸体的面铣。插入件（10）具有自由表面（16）和间隙表面（13A）以及围绕插入件周向延伸的切削刃。插入件的角部具有相对较大的半径，因此当插入件靠近工件的边界线时，在加工发动机缸体期间，设定角度接近零度。自由表面（16）和间隙表面（13A）包围锐角，因此插入物具有正的切割几何形状。在自由表面（16）和切割刃（19）之间设有一个平台（18）。陆地（18）的宽度随着每个插入角度而增加。

摘要： A tool (fig. 1) for chip removing machining, including a basic body (1) and two replaceable cutting inserts (2,3). Each insert (2,3) includes a chip-removing main edge (12,19) situated between a chip surface (38,29) and a clearance surface (39,27). The first insert (2) precedes the second insert (3) during machining of a workpiece. The cutting inserts (2,3) overlap each other in a zone (Z1, fig. 5) defined by a borderline (24) along which a surface generated by the main edge (12) of the first cutting insert (2), with a time delay, is intersected by the main edge (19) of the subsequent, second cutting insert (3). The main edge (19) of the second cutting insert (3) that afterwards intersects the already generated surface, is formed along a chip surface (29) including primary (29a) and secondary (29b) sections, which have different shapes in cross-sections (figs. 8-10) spaced apart along the main edge (19) in order to form a primary part edge (19a) and a secondary, reinforced part edge (19b) arranged to intersect the already generated surface.

摘要： The invention relates to a cutting insert (10) for material-removing machining, especially for milling, turning or punching, with at least one cutting edge (12) and at least one chamfer (15) into which project depressions or recesses (17) adjacent at a distance from the cutting edge and narrow them locally. To permit a very soft cut, stabilise the cutting edge (12) and attain high feeds, there are additional depressions (13) or recesses parallel to the depressions extending to the cutting edge and/or interrupting it for further narrowing the chamfer sections.

Desweiteren ist auch die Spanformleitstufe (3) dieser unterschiedlichen Spanabtragsstärke angepaßt. Dabei verändern sich diese Werte jeweils bezogen auf deren Breite, ausgehend von der Stirnschneide (4) zur Umfangsschneide in einem Verhältnis von ca. 1:4, wobei die Veränderung in der ersten Radiushälfte am größten ist.
